Grab the kiddos and head into Chuck E. Cheese’s tonight for their biggest birthday celebration ever! All kids will get a free slice of cake and a party blower to help break the Guinness World Record for the most people using party blowers simultaneously! This is all happening at 8:40 pm EST / 5:40 pm PST. You might want to get there a little early, though, because the cake is only available while supplies last.
